Which equations could be used to solve for the
unknown lengths of aabc? check all that apply
sin(45") = bc
o sin(45") = 9
be
9 trn(45') = ac
d (ac)sin(45°) = bc
cos(45%) = 10

i do not know this sorry : (

y=mx+b

step-by-step explanation:

m slope

b y-intercept

hello from mrbilldoesmath!

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3
